You shine a laser on a narrow slit 0.221 mm in width. In the diffraction pattern that appears on a screen 5.00 m from the slit, the third minimum is 45.7 mm from the middle of the central bright fringe. Find (a) the wavelength of the laser light and (b) the angle of a line from the center of the slit to the second dark fringe on the screen.

A laser beam is normally incident on a single slit with width 0.580 mm. A diffraction pattern forms on a screen a distance 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.12 mm. Calculate the wavelength of the light (in nm). X Find the relationship among y, the distance from the central maximum to the first minimum, L, and 0, and then apply the equation for the Fraunhofer diffraction pattern. Solve for A. Hint: use a small-angle approximation. nm

Angel is experimenting with a diffraction grating of unknown spacing. He is looking to determine the wavelength of the light in the emission spectrum of a gas and finds that a light having a known wavelength of 623.1nm is deflected by 43.8 ° away from the central maximum in the second order by this grating. Light of the wavelength to be measured is deflected by 45.4° away from the central maximum in the second order. What is the wavelength of this light in nanometers? Please give your answer as a whole number.

The coherence length of an ordinary white light source can be increased if we place a color filter in front of the source, so that the light that passes through the filter is somewhat monochromatic. The minimum wavelength of the emerging light is 546 nm. What is the maximum wavelength in order for the coherence length to be 0.1110 mm?

You illuminate a slit with a width of 78.9 μm with a light of wavelength 731 nm and observe the resulting diffraction pattern on a screen that is situated 2.05 m from the slit. What is the width, in centimeters, of the pattern's central maximum?

In a Young's double-slit experiment, a set of parallel slits with a separation of 0.106 mm is illuminated by light having a wavelength of 587 nm and the interference pattern observed on a screen 3.50 m from the slits.
